Abstract
The invention discloses a method for braze welding of a Cf/SiC composite material and a metal Nb by using a Ti-Co-Nb brazing filler metal. The braze welding method disclosed by the invention is mainly used for solving the current problems that a connecting brazing filler metal for the Cf/SiC composite material and the metal Nb as well as a welding joint obtained by a braze welding connection method are poor in room temperature mechanical properties and can not resist high temperature. The method comprises the steps of: 1, burnishing; 2, cleaning; 3, assembling; and 4, braze welding. The joint obtained through braze welding according to the method has better high-temperature resistance, and the element Nb is added into the brazing filler metal to inhibit the diffusion of a base metal Nb towards the middle layer of the brazing filler metal, so that a better connection is formed. The method disclosed by the invention is used for braze welding of the Cf/SiC composite material and the metal Nb.

fThe method of/SiC composite and metal Nb.
The invention has the beneficial effects as follows: in high-temp solder, than expensive Au base and Pd base solder, Ti base, Ni base and Co base solder then more have practical value.Ti is one of active element the most basic in the active solder, and in order to guarantee the wetability of high-temp solder, the present invention is base with the Ti-Co solder, and both atomic ratios are 1: 1.Ti-50Co(at%) as a kind of high-temp solder, its fusing point is higher, and the joint resistance to elevated temperatures that soldering obtains is better.On the other hand by the binary phase diagraml of Ti-Nb as can be known, Ti and Nb are solid fully molten, thus because mother metal Nb is at high temperature easily added the Nb element by the excessive corrosion of solder in solder, suppressing mother metal Nb to the diffusion in solder intermediate layer, thus the more good connection of formation.
The present invention is used for soldering C
f/ SiC composite and metal Nb.
